Question

At standard temperature and pressure, carbon dioxide has a density of 1.98 kg/m3. What volume does 1.70 kg of carbon dioxide occupy at standard temperature and pressure?

Answer 1

Answer:

volume= 0.85m^3

Explanation:

The density of a substance is defined as the mass per unit volume of the substance, the unit is in kg/m^3 and it is represented by the greek letter rho

Step one:

given data

we are told that the density  of Co2=  1.98 kg/m3

and the mass of Co2 is= 1.70 kg

we know the relation between mass, volume and density is

$density=mass/volume$

make volume subject of formula we have

$volume=mass/density$

substitute we have

$volume=1.7/1.98\\\\volume= 0.85m^3$
